We believe that this effect is due to incompatible hypercolumns, which are not adjacent in the original style, being placed next to each other in \(T\) . Because these features have overlapping receptive fields, the output is optimized to produce the average of several features (each taken from a different region of the style) at a single output location. This manifests visually as a 'washed out' quality, an issue noted by prior work in style transfer [1]}, and other patch-based synthesis work  [2]}, [3]}, [4]}.
